The electromagnetic spectrum spans everything from microwaves through light to heat radiation, including radio, TV, and light.
The color or visible spectrum is a small portion of this that we can see, bounded at short wave length end by violet and ultraviolet and at the long wave length end by red and infrared.

magnetic waves that are developed in TV are energised by the high voltage 2500v to 5000 volt and these generate light waves with colour ,creat colour spectrum
